Application filed September 19, 1902. Serial No. 123,980.

v To all whom it may concer/1t.'

Be it known that we, GLUF Trense, a citizen of the United States, and resident of New York, county of Kings, and State of New York, and LEON LAKE, a citizen of the United States, and resident of New York, county of Kings, and State ofNew York, have invented certain new and useful Improvements in Machines for Removing Cigar-Bunches from Molds, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in machines for removing cigar bunches from molds.

In an application of Oluf Tyberg, filed March 28, 1901, No. 53,211, there is disclosed a machine in which cigar molds are presented in succession to a bunch removing means,the specific form of said means illustrated in the said application being a series of impaling pins,-the molds opened, the bunches removed and the molds closed and discharged.

The present invention has for its object to produce an improved machine of the type disclosed in the application above referred to.

With this and other objects in view, the invention consists in certain constructions and in certain parts, improvements and combinations as will be hereinafter fully described and then specifically pointed outI in the claims hereunto appended.

ln the accompanyingdrawings in which like characters of reference indicate the same parts-Figure 1 is a plan view of the' machine which has been selected to illustrate the invention. Fig. 2 is a front elevation of said machine, certain parts being shown in section. Fig. 3 is a side elevation of said machine, certain parts being broken away. Fig. 4 is a section on the line 4-4 of Fig. 2, and Figs. 5 to 18 are diagrammatic views illustrating the operation of the mechanism.

Referring to the drawings, which illustrate one embodiment of the invention, the side frames of the machine are indicated at 401, said frames serving to support a suitable bed, marked 402, upon which certain of the operating parts of the machine are carried. Inasmuch as the machine illustrated is designed to remove the bunches from a plurality of molds which are operated upon in succession, means are provided for maintaining the plurality of molds in position in the machine. Preferably, however, these means will be such as to maintain the molds to be operated upon in the form of a stack.

While the means for maintaining the stack of molds in position may be of any desired construction, as shown each of the side frames 401 is provided with recesses 403 which are bounded on their rear side by rectangular ribs 404. Extending across the machine from side frame to side frame is a cross bar 405, this bar in connection with the recesses and ribs in the side frames forming a guideway or chute in which a stack of molds may be supported.

The particular means for supporting the stack of molds in the guideway may be varied within wide limits. In the preferred form of the construction, however, these means will be of such a character as to permit the cigar bunches in the bottom mold of the stack to be engaged by the bunch removing means, the mold opened for the discharge of the bunches and then closed and transferred away from the stack, after which another mold comes into position to be opera-ted upon. In the construction shown an abutment is employedupon which the stack of molds may at times rest. This abutment, in the construction illustrated, consists of two movable blocks 406, one of these blocks being located on each side of the machine and each of them being provided with a supporting' shoulder 407. In the preferred form of the construction and as shown each of these blocks is pivoted on a slide 408 which is constructed `to move in suitable ways 409 which may be formed on or secured to the side frames of the machine in any desired manner. `The pivot by which each of the blocks is secured to its slide is marked 410 and each block, for reasons to be hereinafter stated, is preferably held in position bya spring. To this end, each of the blocks is formed with a projection 411 to which is secured a spring 412, the other end of said spring being secured to a pin 413 extending inward fromthe slide before referred to.

The supporting abutment which has just been described will in the preferred form of the construction be utilized not only for the purpose of at times supporting the stack of molds, but will also operate to separate the parts of the lowermost mold ofthe stack. To this end, suitable means are provided for' retainingthe lower part of the lowermost mold on the abutment. While the retain ing means employed may be of any desired construction, as shown each block is provided with a pair of hooked projections 414, said projections being arranged with a space between them. These hooked projections are so constructed as to engage the space formed by the shoulders on the upper and lower parts of the ordinary two-part cigar mold now commercially used, and, in the machine shown, this engagement is effected by giving the projections and abutment an upward movement, the blocks 406 which form the abutment rocking against the stress of the springs 412 to permit this movement.

Vhen, as in the construction illustrated the abutment is relied upon to separate the parts of the lowermost mold of the stack, it is obvious that means must be provided for sustaining in position the upper part of the lowermost mold and the molds in the stack above said part. lVhile these means may be of'any'suitable description, in the construction shown, two supports 415 are employed for this purpose, these supports being in the form of slides and one of them being located on each side of the machine. In the construction shown, each of thesel supports or slides is formed with two engaging projections 416 and 417, and the slides move in ways 418 secured to the side frames. The projections 416 and 417 of the slides 415 are so spaced that when they are iii opera-V tive position the projections 417 which form stack holders will take into the space between the upper and lower parts of the lowermost mold and the projections 416 will take into the same space in a mold above the lowermost mold and preferably the mold next above. The projections 417 are further of such a width as to passinto the space between the retaining projections 414 before described as formed on the abutment 406.

The means for operating the slides 415 may be of any desired description. As shown, there is provided on each side of a machine a pivoted bell crank 419, 420,\piv' oted at 421 in suitable bearings formed on the machine frame. The arm 419 of each bell-crank is slotted and engages a pivoted block 4221mounted in slots in Vthe slides 415.

The arms 420 of the bell-cranks are con nected by links 423 to cam levers 424, said levers being pivoted on each side of the machine and being provided with the usual bowls 425 which engage grooves in cams 426; These cams 426 are mounted on the main shaft 427 of the machine, saidV shaft extending, across the machine from side to side and being supported in suitable bearings in the side frames. This shaft may be driven in any suitable manner, but as shown is provided with a driving' sprocket 428 which may be driven by a chain from any suitable source of power.

It is apparent that when the stack of molds is in position in the machine with the lowermost mold resting on the shoulders 407 of the blocks 406 which form the abutment, the retaining projections 414 of these blocks will enter the space between thc upper and lower portions ofthe mold which rests on the abutment. If, now, the sliding supports be moved inward, it is further apparent that the shoulders 417 of these snpports will lie` between the retaining projections 414 and enter the same spaces which these projections have entered, and that the shoulders 416 will enter similar spaces in the mold above. Attention is directed to the diagram, Fig. 5, in which the parts are shown in the position referred to.` It is further apparent that if the blocks 406 which form the-abutment are given a downward movement the lower part of the lowerinost mold will be pulled downward away from the upper'part of this mold, the upper part and the stack being sustainedl in position by the projections on the slides 415. This position of the parts is indicated in Fig. 6. It is obvious that when the parts of the mold are in this position the bunches lmay be removed by bunch removing means,

a form of which will be hereinafter described, after which by moving` the abutment upward the separated parts of the mold from which the bunches have been removed may be reunited, the projections 416 preventingy the stack from rising as the parts of the mold are brought into engagement.

The movement of` the blocks which compose the abutment is effected through their slides 40S and may be accomplished through any desired connections. These connections however, will preferably be of such a character as to allow them to yield in case a bunch should fail to be removed from the mold or the parts of the mold when they are to be reunited, fail to come truly into register. As shown, each of the slides 408 is connected by means of a link 42S) to a bellcrank lever 430, 431, said bell-crank heilig pivoted by means of a pin 432 to one of the arms 433 of` a bell-crank lever 433. 434 pivoted at 435 to the frame of= the machine. The arms 431 of the bell-cranks 430,431 are further connected by means of springs 436 to the arms 434 of the levers 433, 434. The arms 434 of the bell-cranks 433, 434 aie provided` with suitable bowls 437 which engage cam grooves formed in the inner faces of the cam disks 426 before described. It isv apparent that with the construction which has traer just been described the slides `408 will be moved to give the abutment the movements desired, and further, that should the parts of the mold fail, for any reason, to come truly into register, or there be a cigar bunch interposed between them, the `bell-cranks 430, 431 will rock on their pivots against the stress of the springs 436 and prevent any breakage either in the mold or in the connections.

The bunch removing means employed may be of any suitable character, but preferably will consist, as in the application referred to in the early part of this specification, of a series of impaling pins 43S which may be mounted and operated in any suitable manner. As shown, the bed plate LL02 is provided with a dove-tailed guide 439 on which moves a slide flat() which is provided with a pair of upwardly extending arms dill, 442, said slide and arms forming a carriage. ln the upper ends of the arms eff-ill, 442 there is mounted a shaft di?) which has secured thereto a pair of arms 444;, flel, said arms serving to support a cross bar di@ in which the pins are secured. In the construction shown, the impaling pins are arranged to engage the bunches of the lowermost mold of the stack while said mold is in position in the stack, the present construction being distinguished in this respect from that shown in the application before referred to in which the lowern'iost mold is removed from the stack before the bunches are engaged by tht1 pins.

When, as in the machine shown in the drawings` the pins engage the bunches in a mold which is in position in the stack, it is desirable to effect the engagement of the pins with the bunches by moving the pins. To this end, the carriage above ref-erred to is given a movement toward the stack in order to cause the pins to impalc the bunches, and is then, after the bunches have been impaled and the mold has been opened, given a movement away from the stack to carry the bunches away from the mold. The means by which the carriage is given the movements referred to maybe of any desired description. As shown, the carriage is connected by means of a link 447 to a cam lever 448 which is pivoted on a bar or rod 449 extending acrossI the machine, said rod being carried by the side frames. The .lever fet is provided with a cam stud 4.50 which engages a cam groove formed in a cam disk 451 mounted on the shaft 427.

' Then the impaling pins are given their forward movement to engage the bunches, it is desirable that they be held rigid. While this might be accomplished through the frictional engagement of the gearing hereinafter to be described b vwhich the pins areoperated, there will preferably be provided a locking device so that any unsteadiness resiilting from wear or backlash in the gearing may be avoided While this locking device may be of any desired construction, as shown the cross bar telo has extending rearwardly therefrom notched arms 452, the notches in these arms being arranged to be engaged by the dmvnwardly'bent ends of locking arms 453, said arms being carried on a shaft tijd which is mounted in the carriage before rcferred to. The locking arms 453 may be held in operative position in any suitable manner, as by springs 455, and may be released. in any suitable manner, as, for instance, by rocking the shaft 454. As shown, the shaft provided with a downward] y projecting arm 456 which is arranged to be struck by an arm 457 extending from a boss 458 suitably supported in the machine on a pin 459. This boss 5S has extending from it another arm etti() which is provided with the usual cam roller Lltl which engages a cam slot in a cam 4132 mounted on the shaft 427 before referred to.

After the inipaling` pins have been caused to engage the bunches in the mold and the parts of the mold have been separated, it is desi 'able to give the pins a movement which, in the construction illustrated, is downward, the object of which is to free the bunches from the mold. The means by which the pins are given the movement referred to will depend upon the construction employed for mounting and operating the pins. As sh own` the shaft 443 is provided with a segment 463 which is engaged by a segment 461i formed on a segment lever lt which is pivoted at L66 to the slide Lltd-,0. The lower end of this segment lever is connected by means of a link lo? to a cam lever 468 which is mounted on the cross bar or rod fl-i9 before referred to. This lever 46S is provided with a stud or roller 469 which engages a cam groove in the cam 451 before described.

ln addition to giving the pins the downward movement referred to, the construction which has just been described is also relied upon to effect a movementof the pins which will bring the bunches into position to be discharged from the pins. The contour of the camV groove in the cam L51 is therefore such as to give the pins the downward move ment referred to, after which the carriage moves back to move the bunches clear of the mold. During the backward movement of the carriage, the lever 46S also moves back, keeping the pins in the position in which they stop after the bunches are freed from the mold. After the carriage is moved back sufficiently to carry" the bunches clear of the mold, the movement of the lever 468 is re* versed, causing the shaft L43 to rock in the opposite direction, thus bringing the bunches into discharging position.

The operations referred to will be clear from consideration of the diagrams 5 to 18 inclusive, in which the successive positions of the parts of the mold and the pins are made clear. Fig. 17 shows the pins depositing the bunches in a carrier which as shown consists of a chain 470 which is or may be similar to that shown in the application hereinbefore referred to. After the bunches have been laid in the carrier, the carriage is given a forward movement to withdraw the pins therefrom, the withdrawing action being facilitated by a stripper plate 471 which is or may be similar to that shown in said application.

Before the pins are given the downward movement, the purpose of which is to free the bunches from the mold, the locking levers 453 are operated through the construction which has been described and are disengaged from the notched arms 452. After the locking levers have been disengaged and the pins moved downward the carriage starts on its backward movement. As the carriage moves back, the end of the arm 456 moves away from the end of the striker arm 457, allowing the springs 455 to pull the arms 453 down. This downward movement of the arms is, however, limited by means of a pin 472 which is mounted on the arm 441. The locking levers do not, however, at this time, engage the notched arms, for the reason that the notched arms are below them. Vhen the carriage reaches its rearward position and themovement of the shaft 443 is reversed to bring the pins into the position in which they deposit the bunches, the notched arms 452 would be liable to strike the locking levers 453 if they were not moved out of the way. The bed is accordingly provided with a block 473 which isso located as to be struck by the arm 456 as the carriage reaches the end of its rearward movement. As the arm 456 strikes this block 473, the shaft 454 is rocked and the locking arms move upward so that as the pins swing over the notched projections 442 clear the locking arms. After the bunches have been removed from the mold, the parts of the mold are reunited as has been before described and as is indicated in the diagram, Fig. 7. The mold having been thus emptied and the parts reunited, may be discharged in any suitable manner. Preferably, however, a stacking mechanism is provided for the empty molds, and as each mold is emptied, it is transferred to this stacking mechanism.

The stacking and transferring mechanisms employed may be of any suitable construction. As shown, however, the bed 402 is provided on each side with a bracket 474, each of said brackets being provided with ways in which moves a slide 475. Each of these slides is provided with an upwardly extending projection 476, and the forward end of each of the brackets is provided with einen a stop lug 477. In their rearward position the slides are so located that as the stack of molds moves down the lowermost mold of the stack will rest upon the brackets, the projections 476 of each of the slides being behind the same. The slides are then given ay forward movement which may be effected by any suitable mechanism. As shown, each of the slides has connected to it a link 478, these links being pivoted to cam levers 479 which in turn are pivoted at 480 to brackets 481 on the frame. The lower ends of these levers 479 are provided with cam rollers 482 which engage suitable cam grooves one of which is formed in the cam disk 462 before referred to and the other of which is formed in a Cain 483 mounted on the shaft 427. After a mold has been deposited on the brackets and the slides have been given their forward movement, thus transferring the empty mold from the filled stack, the mold is lifted away from the brackets by a suitable mechanism which is provided for this purpose.

While this mechanism may be of any desired construction, as shown it consists of a pair of lifting slides 484, each of said slides being provided with a head 485. These slides may be operated in any desired manner. In the construction shown, the lower end of each slide is connected by means of a link 486 to a cam lever 487, said levers being mounted on the cross bar 449 before referred to. Each of these levers 487 has an upwardly projecting arm in which is lnounted a cam roll 488, said rolls being arranged to engage suitable cam grooves, one of said grooves being formed in the cam disk 483 and the other in the cam disk 462. As the lifter slides complete their upward movement, the mold is taken by suitable sustaining devices which, while they may be varied in construction, preferably consist of a pair of pivoted pawls 489 pivoted at 490 to the brackets 481 before described and are held forward by means of spring 491 which are connected to projections 492 from the pawls and to studs 493 on the brackets 481. The operating ends 494 of these pawls normally extend inward, lying across the path which the mold takes as it is moved upward by the lifters. The rear ends of the pawls are provided with studs 495 which lie in the path of cams 496 mounted on the periphery of the cam disks 426 before described. These cams are so timed that they swing the rear end of the pawls inward and their operative ends 494 outward just as the mold is caused by the operation of the lfters to pass the ends 494. It will be understood, however, that the operative ends 494 of the pawls are serving to sustain a stack of molds, and the timing of the parts will, therefore, be so arranged as not to move the einem voperative ends of the pavvls out from vunderneath the stack until the mold which is be ing lifted by the lifters comes into position to sustain the weight of the stack, thereby avoiding any excessive drop of the stack.

lt will be seen that the machine which has been described contemplates the transfers of molds as fast as they are emptied from the descending stack of filled molds to an ascending stack of molds and that the two stacks move in parallel lines and very close together. 1n the preferred form of the construction, guides will be provided for the ascending stack which will keep the molds which form it out of contact with the molds of the descending stack. With the construction as before described,these guides will necessarily partly overlie the space through which the filled molds are introduced into the guides which control the movement of the descending stack. Preferably, therefore, these guides will be of such a character as to automatically move out of the Way when the empty stack is removed from them at which time a fresh supply of molds will be added to the descending` stack. While lthe construction of these guides may be widely varied, as shown, they consist of two angular' strips 497, these strips being pivoted at 498 to the `side frames of the machine. Springs 4:99 are secured to projections 500 of the strips and to pins 501 on the frame. produced by the springs is limited in any suitable manner, as, for instance, bya stop 502 mounted on the frame and extending through a perforation in the strips. The lower ends of the angular guides are preferably curved outward as indicated at 508. Withthe construction as before described, it will be seen that as a mold is lifted into the guides they will be turned on their pivots into ope `ative position in which position they partially overlie the space through which filled molds are to be inserted into the machine. As long as there are any molds in the guides they will remain in the position referred to. When, however', the stack of molds is removed from the guides, the springs will swing them out of operative position and clear of the space through which the filled` molds are to be introduced into the machine.

In the preferred form of the construction the entire machine will be tilted backward as is indicated in Figs. 3 and l, so that there is no tendency for the ascending stack of ,empty molds to fall forward out of the ma chine.

While the construction which has been before described is the preferred one, it is to be understood that its details may be varied and that the invention may be embodied in constructions which dider Widely therefrom. The invention is not, therefore, to be lim- The movement of the guides ited to the specific construction which has been hereinbefore described. t
